A mathematical model for the analysis and control of ballast tank blowing and venting operations in manned submarines
نویسندگان
چکیده
The blowing and venting of ballast tanks could potentially be used as a complementary control system to improve the manoeuvrability of manned submarines. To test the feasibility of such a control system, we first propose a mathematical model for these operations. Then, the model is applied to the control of an emergency manoeuvre by using only the blowing and venting of ballast tanks as control mechanism. To this end, we formulate a suitable constrained, nonlinear, optimal control problem where controls are linked to the variable aperture of blowing and venting valves of each of the tanks. The state law is composed of a system of nonlinear differential equations where the equations modeling blowing and venting processes are coupled with the Feldman, variable mass, coefficient based hydrodynamic model for the equations of motion. Numerical results seem to indicate that, indeed, an appropriate use of blowing and venting operations may help in the control of an emergency manoeuvre. Sección en el CEDYA 2011: MAI

Modelling and Control of Blowing-Venting Operations in Manned Submarines
Motivated by the study of the potential use of blowing and venting operations of ballast tanks in manned submarines as an alternative control system for manoeuvring, we first propose a mathematical model for these operations. This model extends previous works where only blowing is considered. Then, the model is applied to the control of an emergency manoeuvre by using only blowing and venting. ...
متن کاملA cost-oriented model for multi-manned assembly line balancing problem
In many real world assembly line systems which the work-piece is of large size more than one worker work on the same work-piece in each station. This type of assembly line is called multi-manned assembly line (MAL). In the classical multi-manned assembly line balancing problem (MALBP) the objective is to minimize the manpower needed to manufacture one product unit. Apart from the manpower, othe...
متن کاملAssembly line balancing problem with skilled and unskilled workers: The advantages of considering multi-manned workstations
This paper address a special class of generalized assembly line balancing in which it is assumed that there are two groups of workers: skilled and unskilled ones. The skilled workers are hired permanently while the unskilled ones can be hired temporarily in order to meet the seasonal demands. It is also assumed that more than one worker may be assigned to each workstation. To show the adv...

Accumulation of sediment transport volume and reduce the useful life of dams, water storage tanks can be. So far, many methods for calculating sediment this is presented in reservoirs are generally classified into two categories: mathematical modeling and experimental .This study examines the effect of using Gstars model parameters in the model, deposition of sediment in the reservoir tank and ...
متن کاملFoil Application to Reduce Resistance of Catamaran under High Speeds and Different Operating Conditions
Today, researchers exploit hybrid craft more than they used to be. The main reason is that they need to high speed as well as extra portability. For instance, a famous hybrid craft is named Hysucat, was designed through the combination of catamaran and hydrofoil. Catamarans, a type of multihull boats, have always considered by designers because of their simultaneous supply of high speed and sta...
